Chlorophyll fluorescence emission of tomato plants as a response to pulsed light based LEDs
E Olvera-González, D Alaniz-Lumbreras… - Plant Growth …, 2013 - Springer
The effects of pulsed light based-LEDs at eleven frequencies (0.1, 1, 10, 50, 100, 500 Hz, 1,
5, 10, 50 and 100 kHz) programmed at 50% duty cycle were analyzed, obtaining important
parameters of the fluorescence emission of chlorophyll such as: maximum fluorescence
(Fm′), minimum fluorescence, the fluorescence emission in steady state, maximum
efficiency of PSII (Fv′/Fm′), the fraction of PSII centers that are open, photochemical
quenching, nonphotochemical quenching (NPQ), quantum efficiency of photosystem II …
